CMB2 is a metabox, custom fields, and forms library for WordPress that will blow your mind.

Plugin available on wordpress.org

CMB2 is a complete rewrite of Custom Metaboxes and Fields for WordPress. To get started, please follow the examples in the included example-functions.php file and have a look at the basic usage instructions.

You can see a list of available field types here.

• Create metaboxes to be used on post edit screens.
• Create forms to be used on an options pages.
• Create forms to handle user meta and display them on user profile add/edit pages.
• Flexible API that allows you to use CMB forms almost anywhere, even on the front-end.
• Several field types are included.
• Custom API hook that allows you to create your own field types.
• There are numerous hooks and filters, allowing you to modify many aspects of the library (without editing it directly).
• Repeatable fields for most field types are supported, as well as repeatable field groups.
• CMB2 is safe to bundle with any project. It will only load the newest version in the system.

• Thanks to many in the CMB2 community and to our friends at wp-translations.org, we have a good start on several translations for CMB2. Please feel free to work with wp-translations.org to provide even more!

• CMB2 Field Type: CMB Attached Posts Field from coreymcollins: custom_attached_posts, for attaching posts to a page.

• CMB2 Field Type: CMB2 Post Search field: post_search_text adds a post-search dialog for searching/attaching other post IDs.

• CMB2 Field Type: CMB2 RGBa Colorpicker from JayWood: rgba_colorpicker adds a color picker that supports RGBa, (RGB with transparency (alpha) value).

• CMB2 Field Type: Google Maps from mustardBees: Custom field type for Google Maps.

  The pw_map field stores the latitude/longitude values which you can then use to display a map in your theme.

• CMB2 Field Type: Select2 from mustardBees: Custom field types which use the Select2 script:

  1. The pw_select field acts much like the default select field. However, it adds typeahead-style search allowing you to quickly make a selection from a large list
  2. The pw_multiselect field allows you to select multiple values with typeahead-style search. The values can be dragged and dropped to reorder

• CMB Field Type: Gallery from mustardBees: Adds a WordPress gallery field.

• Taxonomy_MetaData: WordPress Helper Class for saving pseudo-metadata for taxonomy terms. Includes an extended class for using CMB to generate the actual form fields.
• WordPress Shortcode Button: Uses CMB2 fields to generate fields for shortcode input modals.

If including the library in your plugin or theme:

2. Copy (and rename if desired) example-functions.php into a folder above the CMB directory OR copy the entirety of its contents to your theme's functions.php file.
